place ur hand under the belly and with the other hold its back end so he won' dangle and get all the pressure on its stomach.little dogs are easy but big ones a lot more difficult to get all the legs tucked under.be careful the dog doesn't nip u in the face since u seem to both be nervous. the dog will sense this and be very cautioned. for now just let the dog get use to ur scent and pet and talk gently to him. sit on the ground and let the dog come to you and get to trust u. hopefully he will climb on ur lap and u can go from there. good luck
